High energy & nuclear physics

1 computer, n nodes: one administrator, one scheduler, one power source

• 1 computer, n nodes: one administrator, one scheduler, one power source

• memory: it depends

• Programmer view: one single machine executing parallel codes. Various programming models (message passing, distributed shared memory, data parallelism…)

Use of PCs interconnected by a (high performance) network as a parallel (cheap) machine

• Use of PCs interconnected by a (high performance) network as a parallel (cheap) machine

• Two main approaches

• Dedicated network (based on a high performance network: Infiniband, Fiber Channel, GB-Ethernet...)
• Non-dedicated network (based on a (good) LAN)
